Savages (4:15 p.m., Green stage) vs. METZ (4:45 p.m., Blue stage)The English band’s ‘80s-leaning debut “Silence Yourself” has made them one of the buzziest groups of the year. Enjoy them for a while, then take off; you shouldn’t miss a second of the hard-rocking Canadians, whose razor-sharp guitars are savage in their own right. -- MP

Tree (1 p.m., Green stage) vs. DJ Rashad (1 p.m., Blue stage)Why you gotta put the two local openers on against each other, Pitchfork? What, we can’t enjoy a legendary juke DJ working the crowd of Hold Steady shirt-clad fest-goers into a frenzy AND a fascinating performance from one of the better rappers in Chicago’s new scene? We have to choose? I’m just saying--it’s a conspiracy or something.-- EW

R. Kelly (8:30 p.m., Green stage) vs. TNGHT (8:45 p.m., Blue stage)The advantage would clearly lean toward the Pied Piper of R&B, right? Don’t sleep on Hudson Mohawke and Lunice, however; expect hardcore beats and, since they’ll be coming off of their work on Kanye West’s recent “Yeezus” record, could we see some local appearances? Time will tell. -- EW
